BACKGROUND OF THE PRESENT INVENTION

[0001] 1. Field of Invention

[0002] The present invention relates to a shoe, and particularly to a health-diet sandal which can stimulate the nervous of the human foot for improving the wearer's blood circulation and metabolism.

[0003] 2. Description of Related Arts

[0004] Nowadays, scientists have proved that blood circulation of human foot has been playing a very important part of the human blood circulation system which cannot be forfeited. The distribution of nervous of the human foot has a very close relationship with the nervous of other organs that can affect the cell reproduction of the nervous of other organs and normal operation. In other words, when stimulating the skin under the human foot, a relatively simple reflex is directed to the organs for therapy purpose.

[0005] It is a fact that a normal person will wear shoes for at least eight hours. Therefore, shoe having health care function can help the wearer improving his or her health. For casual wear, the wearer likes to wear a sandal such that some sandals in the market provide a health care function. However, such sandals have several drawbacks.

[0006] Since the sandal is simple in design for wearing, the sandal is taken off from the wearer's foot accidentally, which is an embarrassment for the wearer. However, when complicating the structure of the sandal for securing the sandal on the wearer's foot, the manufacturing cost of the sandal will be relatively increased and thus the sandal has loss a meaning of casual wear. Besides, the sandal usually has a size larger than a size of the wearer's foot, the insole of the sandal may not fittedly in contact with the wearer's foot to stimulate the skin thereof, especially the mid-portion and the front portion of the sole of the wearer. Therefore, such sandals fail to achieve the therapy purpose.

SUMMARY OF THE PRESENT INVENTION

[0007] A main object of the present invention is to provide a health-diet sandal which can stimulate the nervous of the human foot for improving the wearer's blood circulation and metabolism.

[0008] Another object of the present invention is to provide a health-diet sandal which has a size smaller than a size of the wearer's foot for enhancing the insole of the sandal in contact with the wearer's foot for stimulation purpose.

[0009] Another object of the present invention is to provide a health-diet sandal, wherein a height of the sandal is gradually increasing from a front portion to a rear portion such that the wearer tends to lift up his or her heel when wearing the sandal, so as to strengthen the stimulation to the toes.

[0010] Another object of the present invention is to provide a health-diet sandal that continuously provides adequate magnetic field arranged to penetrate through the wearer's foot for further improving the wearer's blood circulation and metabolism.

[0011] Another object of the present invention is to provide a health-diet sandal, wherein no expensive or complicate mechanical structure is required to employ in the present invention. Therefore, the present invention successfully provides an economic and efficient solution for therapy purpose.

[0012] Accordingly, in order to accomplish the above objects, the present invention provide a health-diet sandal which comprises a shoe sole having a heel portion adapted for biasing against an arch portion of a wearer's foot, and a shoe body comprising a vamp attached on top of the shoe sole to define a foot chamber between the vamp and the shoe sole, and an elongated elastic unit having two ends extended from two sides of the vamp adapted for mounting behind a heel of the wearer's foot, so as to hold the wearer's foot within the foot chamber in position.

[0014]FIG. 2 is a side view of the health-diet sandal according to the above preferred embodiment of the present invention, illustrating a wearer wearing the health-diet sandal.

[0015]FIG. 3 is an exploded perspective view of the health-diet sandal according to the above preferred embodiment of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0016] Referring to FIG. 1, a health-diet sandal according to a preferred embodiment of the present invention is illustrated, which comprises a shoe sole 10 having a heel portion 11 adapted for biasing against an arch portion of a wearer's foot and a shoe body 20 comprising a vamp 21 attached on top of the shoe sole 10 to define a foot chamber 22 between the vamp 21 and the shoe sole 10 and an elongated elastic unit 23 having two ends extended from two sides of the vamp 21 adapted for holding the wearer's foot within the foot chamber 22 in position.

[0017] As shown in FIG. 2, the shoe sole 10 has a size smaller than a size of the wearer's foot in such a manner that when the wearer wears the health-diet sandal, the heel portion 11 of the shoe sole 10 is positioned at the mid-portion of the wearer's sole. Therefore, due to the weight of the wearer, the heel portion 11 of the shoe sole 10 is bias against the arch portion of the wearer's foot to stimulate the nervous distributed thereon. It is worth to mention that when the wearer wears the conventional sandal having a size larger than the size of the wearer's foot, the arch portion of the wearer's foot may not be pressured by the conventional sandal.

[0018] Accordingly, the nervous distributed around the arch portion of the human foot directly reflexes to the human organs which are stomach, kidney, spleen, pancreas, duodenum, large intestine, small intestine, urinary pipe, urinary bladder, and knee. Therefore, it is unreasonable to ignore the stimulation of the nervous distributed on the arch portion of the wearer's foot.

[0019] The shoe sole 10 further has a front toe portion 12 having a height smaller than a height of the heel portion 11 to define an inclined top surface of the shoe sole 10. Therefore, when the wearer wears the health-diet sandal, the center of mass of the wearer tends to move to the front. In other words, the wearer inclinedly stands on the ground with an inclined angle approximately 27.5 degrees. Thus, the weight of the wearer is distributed on the wearer's toes to bias against the shoe sole 10 so as to strengthen the stimulation to the toes. Besides, when the wearer wears the health-diet shoe, the heel of the wearer's foot is lifted up, which will stimulate the calf and the buttocks, so as to keep the wearer's body slim.

[0020] As shown in FIG. 3, the shoe sole 10 comprises a base 13 having a plurality of magnet cavities 131 spacedly provided thereon and an insole 14 affixed on top of the base 13 to enclose the magnet cavities 121, wherein the insole 14 has a corresponding size smaller a size of the base 13. The insole 14 should be made of fabric having a ventilation ability since the wearer usually do not wear sockets when wearing the sandal such that the wearer will feel comfortable when using the present invention.

[0021] According to the preferred embodiment, the vamp 21, which is made of fabric such as leather, has two side edges affixed to two side portions of the shoe sole 10 wherein the two side edges of the vamp 21 is rigidly affixed between the base 12 and the insole 13 by stitching.

[0022] Accordingly, the elastic unit 23 comprises at least a resilient element 231 arranged to lengthen the elastic unit 23 so as to adjustably mount on the rear side of the heel of the wearer. As shown in FIG. 3, elastic unit 23 comprises two elongated side straps 232 each having an end extended from the respective side of the vamp 21 and an elongated back straps 233 adapted for mounting behind the heel of the wearer's foot wherein two resilient element 231 are affixed between the side straps 232 and the back straps 233 respectively.

[0023] The shoe body 20 further comprises an attaching means 24 for detachably attaching the elastic unit 23 to the vamp 21, wherein the attaching means 24 comprises a pair of first fasteners 241 affixed to two ends of the elastic unit 23 and a pair of corresponding second fasteners 242 affixed on two sides of the vamp 21 in such a manner that the elastic unit 23 is detachably affixed to the vamp 21 by detachably connecting the first fasteners 241 to the second fasteners 242 respectively.

[0024] Accordingly, the first and second fasteners 241, 242 are a pair of snap fasteners provided on the elastic unit 23 and the vamp 21 respectively. It is apparent that the first and second fastener 241, 242 of the attaching means 24 can be replaced by other fastening elements such as buckle fasteners.

[0025] In order to further enhance the therapy purpose of the present invention, the health-diet sandal further comprises a plurality of magnet elements 30 for providing a magnetic field around the wearer's foot and arranged to penetrate through the wearer's foot for further improving the wearer's blood circulation and metabolism.

[0026] Each of the magnet elements 30 is fittedly disposed in the magnet cavity 131 of the base 13 of the shoe sole 10, wherein glue may be applied to firmly stick the magnet elements 30 in the magnet cavities 131 respectively.

[0027] As shown in FIG. 3, there are three magnet elements 30 specifically located on the shoe sole 10, which is the heel portion 11, the toe portion 12, and a position therebetween, to form a triangular magnetic configuration. Each magnet element 30 is capable of producing a magnetic field having intensity between 70 and 3500 gausses. For a wearer who is sensitive to the magnetic field, the magnet elements 30 having weaker magnetic field which is between 70 and 100 gausses can be used.
